ABSTRACT: The aim of this study was to investigate the effects of a post-weaning isocaloric hyper-soybean oil diet on later obesity and explore the underlying mechanisms. In the present study, newborn male Wistar rats were weaned on d 24, divided into CON (control), HC and HSO groups. CON was assigned to AIN-93G diet (a hypercarbohydrate diet, for short HC diet) during the entire experiment. HC and HSO were fed with HC and isocaloric hyper-soybean oil (HSO) diet for 3 wk respectively, fed with HC diet for 2 wk successively, finally administrated high fat diet (HF) for 6 wk to induce obesity. On 3,5,11 wk, the body weight, body fat content, blood glucose, blood lipid, serum insulin and leptin levels and obesity-related gene (CPT-1, FAS, UCP2, UCP3) expression levels in rats were detected. It was shown that body weight, body fat content, blood glucose and blood lipid, serum insulin and leptin levels in HSO were down-regulated on 3 and 5 wk, therefore were significantly reduced on 11 wk vs. HC. The CPT-1, UCP2, UCP3 gene expressions were up-regulated but FAS were down-regulated persistently in HSO. The study indicated that an early isocaloric HSO diet may reduce later obesity risk and reduce blood lipid and glucose abnormalities in adulthood via persistently influencing insulin and leptin sensitivity and permanent regulation of obesity-related gene expressions.Asia Pacific Journal of Clinical Nutrition 01/2007; 16 Suppl 1:368-73.
